I too have just started adding macros and micros to my tank via 2 Peristaltic pumps from APTinstruments and am doing a PPS style of fertilization. I have been trying to perfect the amounts of nutrients in my stock solutions and would love to know the specifics of your solutions Brilliant. Can you list the amount of nutrients in your stock solutions and how much you add to your tanks ml/gal?

I've been setting my pumps to turn on 1x daily before my lights turn on for 1 min with my Aquacontroller Jr. They dispense 7ml/min with the size hose being used. It would be possible to slow down the flow rate considerably with a smaller pump hose and have it come on multiple times per day but I don't think it's necessary. The nutrient levels in the water are always in the correct range even at the end of the day and we're just trying to replace the nutrients that were used the day before.

I have been using this method for 2 weeks now and my plants are already starting to look healthier and have new growth.The best thing I could do was automate the system because for me, remembering to fertilize everyday was very hard and I my fertilizing schedule was inconsistent. Now I know exactly what the tank is getting every day.

Thanks for the link...it should help with my adjustments.
